I agree with Hystearical. The more you look, the better the odds are you will find something to get you in the proverbial door. Expand your search area? Increases the odds. Expand what you're prepared to do? Really increases the odds. LIfe is really nothing but playing the odds (oh gawd....not this old guy with his experience bullshit).
Not sure where you live but check day labourer, resource based grunt work, hell, even guys who deliver and pick-up porta-potties are making around $30/hr because no one wants to do it - and all you need is a driver's license and a strong stomach. My advice is to forget about finding a job that you want to do; first, get any job, then look around for what you like - or at least like better than what you are doing at the first job. It is much easier to get a job if you already have one.
Also, give your family some credit. They may not consider you a burden. I know lots of families where the "attempt" even if it results in failure is more valued than not trying at all.
Finally, if a potential spouse cannot see you as a quality person without having a good job, then that is not a life-partner but just another asset. They would leave the instant things get hard or there is a down-turn in your socio-economic status. Just like a fancy car or boat will get repossessed (i.e. leave) if you hit a difficult time, the spouse would be gone also. Find someone who sees you as a good person working hard to get better. I'm a lawyer with my own firm now, but prior to that I worked heavy construction, bounced at a night-club and even cleaned crew shacks and bathrooms at remote work sites (jeez, that really sucked - seeing crotch spiders in the showers and lord knows what in the toilets).
So, feel sorry for yourself this week-end, then first thing Monday, get up, dust yourself off and see if you can find a job that sucks - remember, it's only a stepping stone to something better. You got this.
